SN74LV573DW

Latches Overview

The SN74LV573DW is an octal transparent D-type latch manufactured by Texas Instruments, belonging to the LV logic series. It features eight D-type latches with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 2 V to 5.5 V and supports a wide operating temperature range from -40°C to +85°C. Propagation delay varies with voltage, specified at 18.7 ns at 2.5 V, 14.5 ns at 3.3 V, and 8.8 ns at 5 V. Static current is typically 20 uA, with output drive capabilities of 32 mA low-level and -16 mA high-level.

Latches Feature Summary

• Provides eight independent transparent D-type latches for data storage applications
• Features three-state outputs to facilitate bus-oriented architectures
• Supports wide supply voltage operation from 2 V to 5.5 V

Latches Applications

• Bus-oriented systems requiring data latching
• Clock buffers and drivers
• Register files in digital logic circuits

Latches Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to confirm technical parameters match your design constraints before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with three-state control over a wide voltage range. Compare propagation delays across different supply voltages to ensure timing margins are met. Consider the SOIC-20 package dimensions for PCB layout compatibility and thermal management requirements relative to similar logic families.

Latches Part Context

This part belongs to the SN74LV573A family of octal transparent D-type latches. It shares functional similarities with other Texas Instruments logic devices but is distinct in its low-voltage CMOS technology and specific pinout configuration. The DW suffix indicates a 20-pin Small Outline Integrated Circuit (SOIC) package with a standard lead pitch.
